I received the RCV solenoid valve today. It came with new hoses and clamps, which is very nice. I installed it, which isn't too hard, getting the vacuum hoses off and back on was the toughest part. I cleared the code and took it for a spin.
Problem solved! No more BOV fluttering or CEL. I drove it for about a 1/2 hour and checked for pending codes when I got home, but there were none. I'm wondering if the BOV and RCV often fail together. If someone else runs into this problem, I would suggest replacing both. It's about $150 for both parts and since they are close together, the extra labor is minimal.
